Each year the public is being introduced to bigger and better television sets. Some concern has been expressed that the greater power needed to operate these sets will generate soft X-rays which may escape, and so add to the general background of radiation to which we are all now exposed.
Happily this is a groundless fear, because a very simple technique is available to ensure complete safety from hazards of this nature. X-rays emanating at this intensity can be effectively absorbed by thin lead foil which is readily available in this country. It can be pasted, after the fashion of paper, on the inside of a cabinet before the electronic components are assembled or, alternatively, incorporated into the body of the cabinet which is often of plywood construction.
Finally, the sheet of armour-plated glass placed in front of most television tubes can be made of lead glass, following the principle adopted by atomic scientists when dealing with this problem. In this way manufacturers can ensure that the whole set is completely encased in lead and so achieve absolute security.
